Calcium Boost

Advanced soluble calcium fertilizer supplement — corrects calcium deficiencies, strengthens plant cellular membranes, and prevents physiological disorders including bitter pit, blossom-end rot, and fruit cracking.

Vegalab Calcium Boost
Naturally derived · Non-toxic

Calcium Boost delivers soluble, immediately plant-available calcium in a formulation enhanced with amino acids, organic acids, and pyroligneous liquor — a biostimulant complex that improves calcium mobility within the plant. Calcium is the foundation of strong cellular walls: deficiency leads to soft fruit, poor shelf life, and damaging physiological disorders such as bitter pit in apples, blossom-end rot in tomatoes, and brown rot in stone fruits. Applied 2–3 times across the cropping season, Calcium Boost prevents these disorders while improving root development, membrane integrity, and overall crop quality.

Key benefits
  • Effectively treats and prevents calcium deficiency across a wide range of crops.
  • Strengthens cellular membranes and plant cell wall integrity for firmer, higher-quality fruit.
  • Prevents bitter pit, blossom-end rot, brown rot, and fruit cracking.
  • Promotes root development for improved anchorage and nutrient absorption.
  • Amino acid chelate enhances calcium mobility and uptake efficiency.
  • Pyroligneous liquor acts as a biostimulant to support overall plant metabolism.

Application rates

Standard foliar spray

Mix 4.7–7.6 ml (1–1½ tsp) per gallon of water (1:800 to 1:500). Apply 2–3 times throughout the cropping season whenever deficiency symptoms appear.

Prevention program

Begin applications at early fruit set and repeat at 10–14 day intervals during periods of rapid fruit growth and high transpiration demand.
